Particularly suited for medium to higher air flow volumes against high resistance in exhaust air systems of process technology or commercial kitchens.


  • High reliability TEFC or ERM motors with sealed for life bearings
  • Class ‘H’ available across all sizes
  • EXE, EXD, motors available across the range
  • High performance backward curve centrifugal impellers
  • Perfectly suited to medium/high volume and pressure applications
  • Fully speed controllable
  • Fans can be mounted at any angle

The ILSC series is a range of inline duct mounted fans for use in general ventilation systems. All models are built around high performance centrifugal impellers driven by totally enclosed fan cooled (TEFC) or external rotor motors (ERM). Note that single phase ILSC series fans are only available in ERM models.


Cases are fabricated from galvanised sheet steel with standard duct flanges for easy installation. Impellers are high efficiency backward curve centrifugal type. The impeller and motor assembly is supported by a robust galvanised steel frame for long, trouble free service.


Motors are of TEFC or ERM design. Motor enclosure feature minimum IP54 protection as standard with higher ratings are available on request. Motor windings incorporate class ‘F’ insulation as standard although class ‘H’ is readily available. Motor bearings are sealed for life and maintenance.
